What is the potential of Renewable energy sources in addressing security of energy supply concern? The case of Nigeria

Nigeria is largely dependent on Oil as the major source of Energy and basis for Government Revenue, this has accentuates its Vulnerability to the repercussion of the imminent Oil depletion. Hence this paper examined individually the potentials of the five (5) major Renewable Energy Sources (Hydro, Wind, Solar, Biomass and Geothermal) and discussed their viable roles as alternative Energy Sources in tackling the Security of Energy Supply concern in the country. From the discussion it was observed that Nigeria has great potentials of Renewable Energy Sources but not effectively utilized, therefore, there is need for an urgent and necessary actions to develop and provide a level playing ground for Renewable Energy Sources to adequately served as a clean alternative Energy sources in the country.
